255 hours / 85 hours = 3.
This means that the bacteria will double in size 3 times.
900,000 × 2 = 1,800,000
1,800,000 × 2 = 3,600,000
3,600,000 × 2 = 7,200,000
After 255 hours, the colony of bacteria will be 7,200,000
Your goal is to isolate the x variable, so all you have to do here is subtract 6 on both sides.
Your final answer is x ≤ 2.
Hope this helps a lot! :)
what is the question. I am kinda confused what you want me to solve. Please state the question more clearly.
